NOTE:
As one can plainly see, in the case of Mercury, there are
multiple perigee/apogee events per calendar year, as many
as three of each and sometimes one extra event.

For the perigee/apogee events of the year, there will be
a closest perigee and a greatest apogee value.

Mercury is constantly moving either towards or away from
Earth, except at the perigee/apogee points, where it mo-
mentarily stands still, then its radial distance reverses
trend.

NOTES:

[1] This Mercury perigee and apogee calculator spans
    the 9799 year period from 200 AD to 9998 AD.

    It was written in PHP v7.4.9 and makes internal
    calls to the NASA/JPL Horizons API.


[2] Occasionally a time-out may occur if the Horizons
    server is temporarily unavailable or too busy and
    an error occurs.

    If such a crash or hang-up does occur, simply re-
    fresh and try again.



[3] UT1 = Old Universal Time Scale - Solar based.
          Old previous UT time scale used for years up
          to 1961.

    UTC = Coordinated Universal Time Scale. Atomic-based.
          Newer UT time scale used from 1962 to date.
          World times are now based on this standard.

    LT  = Local Time for the given time zone based on
          the given +/− HH:MM offset.

          Time Zone Offset Convention:
          West of Greenwich, offsets are negative.
          East of Greenwich, offsets are positive.

          Standard Times are Assumed.
          Add 1 hour for Daylight Saving / Summer Time
